Abstract (en)
During the period between the start of steering t1 and an instant t2 when a prescribed interval TM1s has passed, the drive torque of a motor for driving a vehicle wheel is as shown in (a) corrected so as to be a value which is temporarily increased from the intended motor torque by just the amount indicated by the solid line waveform in (a); and during the period between t2 and an instant t4 when a prescribed interval TM2s has passed, the drive torque of a motor for driving a vehicle wheel is controlled so as to be a value which is temporarily decreased from the intended motor torque by just the amount indicated by the solid line waveform in (a). The motor torque decrease correction during the period t2 - t4 (the intermediate stage and the last stage) effect an inner and outer wheel load change which speeds up the roll speed; as indicated in (b), the inner and outer wheel side shock absorber / stroke speed Vsabout and Vsabin become faster than the Vsabout' and the Vsabin' when motor torque decrease correction is not executed. Hereby, the vibration damping force (roll suppressing force) of the shock absorber becomes larger and the roll angle can be made small during the period t2-t4 as shown by the solid line in (c), thus improving the feeling of rolling of the vehicle body while steering.
